Cannot install .msi file without using cmd line with admin rights

Running on a Windows 7 SP1 within a domain using local admin rights.

Download the client install file for WPKG (WPKG Client 1.3.14-x64.msi) and found it 'blocked' in the file properties.  I unblocked the file and proceed to install it locally - just click and install.  The install fails - need admin rights, but... I'm already the local admin to the PC.  Open a CMD line with admin rights - install without error.

Best I figure is Windows still doesn't trust the file, even after the unblocking.

In the properties and compatibility tab 'run this program as an admin' is grey out.    In security, I'm list with full control except 'special permissions'.  Changing these rights is greyed out.

Tried using unblock in PowerShell and streams to strip off anything.  Give me a new run error - A network error occurred while attempting to read from the file.

I've seen this with other file Windows might consider sketchy, but this one really bothers me.  I don't want to have install this client on each workstation manually.  I can't get Group Policy to push it out either.

Anybody help me how on the mechanics behind this protection and how to get Windows to trust it?  One of the security settings in IE?  Need a trusted publisher cert?  Thanks for your time.

First I would turn off UAC if you haven't done so.  See the article below:

Also, if you have the domain admin username and password, try navigating to the MSI you want to install via Windows Explorer.  Hold down the shift key and right-click the MSI and choose "Run as different user."  Run it as the domain admin account.

Cambo84,

Using domain admin privileges, using 'Run as Different user'.  But after enabling 'Do not preserve zone information in file attachments' in the local group policy and re-downloading the client .msi file it started working.

If I can install as domain admin.  Group policy install should be possible now.

Thanks.
